Lightweight and compact, the SU Black/Silver Dual Port Blow Off Valve bolts directly to the factory mounting points with no specialized tools needed. Supplied with a “screw-in” blanking plug for easy conversion to a fully recirculating (Plumb Back) or a fully atmospheric (Supersonic) BOV.

The Compact valve features sequential recirculating/atmospheric ports for total flexibility, tool-free adjustment via a rotating cap and a 360 degree rotating nipple.

The Compact Dual Port Blow Off Valve is three BOVs in one. The Dual Port can be configured to vent to the atmosphere (VTA), recirculate into the air intake or BOTH! This blow off valve is also adjustable allowing you to tune the BOV to meet the needs of your car. This is done simply by a turn of the hand. No tools are required to adjust the stiffness of the blow off valve. The recommended setup for TurboSmart Blow Off Valve kit on the WRX/Legacy is the Dual Port option. Using the Dual Port setup, the BOV will recirculate under low boost driving. During high boost situations, the BOV will VTA and recirculate into the intake.

Benefits of the TurboSmart BOV Kit over ALL other BOV kits:

• Recirculates under light boost/normal daily driving conditions

• VTA and recirculates under high boost conditions or compression surge

• BOV spring rate is tunable to the vacuum of your car

• No stalling or backfiring when adjusted properly

• 3 in 1 BOV: VTA in tandem with Recirculation (recommended), 100% Vent to Atmosphere, or 100% Recirculation

• Holds more boost over stock valve
